freeze-core is cx_Freeze's bootloader/support library: on Linux its only native component is a small bootloader executable compiled from portable C (console.c/_common.c + a generated frozen-module source), built per interpreter via setuptools - no prebuilt bootloader binaries, which is why upstream ships one wheel per cp3NN ABI. Mirrors upstream's own sdist then cibuildwheel recipe, overriding only the build selector and the riscv64 manylinux/musllinux images; testing reuses upstream's own wheelhouse-based test fixture on the manylinux leg.

Upstream's pyproject.toml pins [tool.cibuildwheel.linux] archs to "x86_64 aarch64 ppc64le", so every build job selected zero identifiers and failed with "No build identifiers selected". Set CIBW_ARCHS=riscv64. The test_wheels matrix had no python axis, so its include entries overwrote each other and only a single cp314t job was generated. Add the python axis so each include attaches python-version to its own job. Install the built wheel in the same resolve as cx_Freeze so uv does not build the newest freeze-core sdist from source on the runner first.

freeze-core0.7.2Compiles cx_Freeze's bootloader support library: a small executable (
freeze_core.bases.console) linked against libpython, built from portable C plus a generated frozen-module source. Upstream publishes no riscv64 wheel.Mirrors upstream's own
build-sdist.yml+build-wheel.yml.Differs from upstream
./wheelhouserelative path and upstream tests the same way, outside cibuildwheel.Testing
tests/test_208.py: freezes a sample app with cx_Freeze and runs the frozen executable. Skips musllinux - no musl riscv64 image elsewhere in this repo to test against.License: OK
Built on cp312; 1 passed, 15 skipped (Windows-only tests).
